The usefulness of the 28-item General Health Questionnaire (GHQ) in detecting psychiatric comorbidity in a sample of hospitalized gastroenterology patients was tested. Validity coefficients were determined by comparing the results of the GHQ with findings from a psychiatric interview. At the best discriminating score (8/9), the GHQ yielded a sensitivity of 77%, a specificity of 75%, a positive predictive value of 67%, and a misclassification rate of 24%. The GHQ did not accurately identify alcohol dependence and abuse and did not discriminate between patients with anxiety disorders and those with depressive disorders. Despite its limitations, the GHQ, if supplemented with specific questions about alcohol abuse, can effectively screen medical inpatients for psychiatric disorders.
对28项一般健康问卷(GHQ)在检测住院胃肠病患者样本中的精神疾病共病情况的效用进行了测试。通过将GHQ的结果与精神科访谈的结果进行比较来确定效度系数。在最佳区分分数(8/9)时,GHQ的灵敏度为77%,特异度为75%,阳性预测值为67%,误分类率为24%。GHQ不能准确识别酒精依赖和滥用情况,也无法区分焦虑症患者和抑郁症患者。尽管有其局限性,但如果补充关于酒精滥用的特定问题,GHQ可以有效地筛查住院患者的精神疾病。
